Title: Insoluble resinous copolymers of (chloromethyl) styrene and polyvinyl aromatic hydrocarbons and nitrogen-containing derivatives of the copolymers
IPC: C08F8/32
Filed: 1956-04-23
Abstract: Copolymers are prepared by polymerizing a mixture of a major amount, on a molar basis, of ar-chloromethyl styrene and a polyvinyl aromatic hydrocarbon.  Divinyl-benzene, xylene, ethylbenzene, ethyltoluene or trivinylbenzene may be used as cross-linking agent.  Up to 10 per cent of styrene, vinyl toluene or xylene, a -methyl styrene, ethyl acrylate, methyl methacrylate, methyl isopropenyl ketone or vinyl chloride may be included in the mixture.  The copolymers may be prepared en masse or in suspension in glycerine, water or brine, containing methyl cellulose (Example (1)), bentonite, a diethanolamine-adipic acid condensation product and an ethylene oxide-ureaformaldehyde condensation product (Example (2)), using catalysts such as acetyl, benzoyl, lauroyl, stearyl and di-t-butyl peroxides and di-t-butyl diperphthalate, t-butyl perbenzoate and cumene hydroperoxide.  The copolymers may be aminated to form anion-exchange resins by suspending in liquid ammonia or amines such as methyl, ethyl, butyl, dimethyl, diethyl, dipropyl, trimethyl, triethyl, tributyl amines, ethylenediamine, diethylenetriamine, dimethylethanolamine, methyldiethanolamine, dimethylisopropanolamine, methyldiisopropanolamine, benzyldimethylamine, diethylcyclohexylamine, preferably after swelling in liquids such as benzene, toluene, chloroform, carbon tetrachloride, methylene chloride or perchlorethylene or by adding the aminating agent to the copolymer in suspension in water, benzene, toluene, chlorobenzene or perchloroethylene.

Abstract: 1,138,478. Slide projector. VOIGTL€NDER A.G. March 23, 1966 [March 23, 1965], No.12869/66. Heading G2J. A slide-projector 1 having a compartmented magazine 2 from which slides D are removed and returned by slide-changing member 6, has a sliding member 12 having deflecting members 13 thereon which are moved, during the slide changing operation, into the range of the slides such that they push aside the slides on either side of the slide to be projected such that the slide-changing member 6 contacts only the one slide. The slidechanging member 6 has a slot 17 in which is fixed a pin 18 attached to a shift gear wheel 19 which rotates freely about shaft 20. The shaft 20 supports another gear wheel 22 on which is fixed a pin 23 which moves within a slot 26 on a side arm 27 of the sliding member 12. The shift gear wheels 19, 22 are each driven by gear wheels 35, 36 respectively which are driven by a motor driven coaxial pulley 37. The gear wheels 35, 36 have sections without teeth such that, on operation of the driving pulley 37, the slide changing member 6 first returns the slide D and the magazine is then moved on one advance, the sliding member 12 then moves the deflecting members about the slide D Fig. 7 (not shown) and the member 6 removes the slide to the projection position. When used with circular magazines, a leaf spring 29 is fitted on slot 26 such that when the deflecting members are stopped by contacting the slides, the spring 26 yields to the pin 23.

[Also in Division D2] A baby's napkin is at least partly composed of sheet-like fibrous, moisture absorbent material 2, within and/or on which minute pressure rupturable capsules 4 are distributed and retained, each capsule having a wall of polymeric material releasably containing baby oil. The oil is a colourless oil with lanolin, and may also contain perfumes, deoderants, silicone oils and disinfectants, while the capsules are preferably of gelatin-gum arabic material easily ruptured in use of the napkin. The obsorbent layer 2 of the napkin may be made of porous paper or other cellulosic fibre, or of other fibrous material, and the capsules, which may be distributed singly or in clusters, preferably form 20-45% of the total weight of the napkin. The capsules may be bonded to the material by a flexible binder 6 such as polyvinylchloride or polyethylene. Further embodiments, Figs. 2, 3, 5, 6 (not shown), have the capsules wholly within the absorbent layer 2, thereby avoiding chaffing by broken capsules. Methods of distributing capsules within and on the absorbent material are described, and specific examples given of capsule and cluster sizes, and capsule wall thickness. A suitable baby oil formulation and alternative capsule materials are also given.

Filed: 1943-08-12
Abstract: 566,443. Tools. O'NEILL, J. Aug. 12, 1943, No. 13045. [Class 83 (iii)] A tool for axially slotting tube ends which are left in boiler tube plates after the tubes have been burnt off, to facilitate their removal from the plates, consists of a cylindrical body 1 which is a loose fit in the tube and carries a cutter 5 projecting therefrom so as to cut the slot in the tube, without damaging the tube plate, when driven through the tube, e.g. by a percussive hammer. The cutter may be triangular in cross-section so as to fit a dovetailed slot 3 in the body 1, a shallow groove 8 being provided in the body to receive an ejecting tool for removal of the cutter which may be turned to cause any of its three edges to form the cutting edge or may be turned end for end to provide six cutting edges in turn. The tool is used to cut two parallel slots in the tube, after which the intervening strip of metal may be removed and the tube end then collapsed to loosen it from the tube plate. In a modified construction, the cutter 25, Fig. 7, is pivoted by a pin 26 in a slot 23 of the body 21 and has a V-shaped cutting edge 27 projecting beyond the surface of the body when it meets a shoulder 29 of the slot 23. In this position the cutter will form a slot in a tube end, but on withdrawal of the tool from the tube the cutter will pivot about the pin 26 and lie wholly within the slot 23.

Cleansing-compositions.-Saponaceous compositions for use with sea-water or in dyeing, fulling, or other baths which are acid or contain salts of calcium or magnesium consist of mixtures of soaps or turkey-red oils with an aromatic or hydro-aromatic sulphonic acid or salts thereof of high wetting power. There may also be added sulphite cellulose liquor, a purifying agent e.g. borax, or solvents such as benzine, glycerol, cyclohexanol, alcohols, or ethylene glycol monoethyl ether. The compositions may be prepared by mixing the acid or its salt or a concentrated solution thereof with fused soap, or kneading or mixing the soap and dry salt together, or by adding the acid during the saponification. 80 lb. of soap to 20 lb. of acid or salt is suitable. Sulphonic acids specified are those obtained by condensing aromatic or hydro-aromatic sulphonic acids with aliphatic, hydro-aromatic, or aromaticaliphatic alcohols such as isopropyl or butyl alcohols, cyclohexanol, or benzyl alcohol; condensation products of formaldehyde with naphthalene sulphonic acids; sulphonic acids containing halogen, nitro-, amino-, or hydroxyl groups e.g. amyl naphthylamine sulphonic acids. In examples (1) a product for fulling or washing goods is obtained by kneading or boiling together 50 kilograms of soap, 50 kilograms of butyl naphthalene sulphonic acid, and 20 kilograms of concentrated sulphite cellulose lye. (2) 10 kilograms of soap are mixed with 25 kilograms of isopropyl or butyl naphthalene sulphuric acid sodium salt. A solution of 1-2 grams is added to each litre of a carbonizing bath. (3) A composition for washing, degreasing, and bleaching wool consists of 6 lb. of grain or resin soap, 10 lb. of butyl naphthalene sulphonic acid, and 4 lb. of sodium bisulphite. 16 grams is added to each litre of an acid bath. Dibutylaniline sulphonic acids, condensation products of cresol-sulphonic acid with formaldehyde, and sulphonated anthracene residues and the like may replace the above sulphonic acid. Sulphonic acids of "high wetting power " are defined as those of which 0.5 per cent aqueous solutions of their sodium salts wet a felt-like textile fabric, e.g. of wool or cotton, within an hour. The sulphonic acids referred to may also be used in baths in the manner described in the parent Specification. Specification 19759/12 also is referred to.
